Today we present our Mukluk line, updated for 2013.
At Salsa we don't view fatbikes as only being about snow and sand, but as extremely capable all-season, all-terrain performers. For 2013, we've made some changes to our popular Mukluk frame that help transform the Mukluk into the ATB of bicycles.
This frameset carries over unchanged for 2013. It retains the 2012 geometry and standard 34mm headtube, and continues to feature our Alternator dropouts, and will only be availabe as a Complete Bike.
Frame Updates For Mukluk 2 & 3
2013 Mukluk 2 Complete Bike: White/Lime Green
For 2013, we've added our super-versatile Alternator dropouts to our aluminum Mukluk frames. The Alternator dropouts allow for multiple drivetrain options and adjustable chainstay length/tire clearance. It's now possible to set the Mukluk up as a true singlespeed, or even configure a singlespeed drivetrain after a log rips off your rear derailleur during that bush-whack ride. The Alternators are also incredibly durable. They've made multiple trips down the Great Divide Mountain Bike Route. In fact, just this summer, our sponsored rider Kurt Refsnider and his partner Caroline rode the Tour Divide on our prototype tandem equipped with Alternators.

Another new feature for our aluminum Mukluks is a 44mm headtube. The primary reason for this change is to allow for the use of both straight 1-1/8" forks and tapered 1.5" forks. There are several new fatbike forks out there (including our new Beargrease fork) that come in tapered form. Additionally, since the Mukluk is also compatible with 29er wheels (135mm front and 170mm rear spacing needed), it keeps the option open to use the latest and greatest suspension forks.
Lastly, we've switched to toptube cable routing via triple guides. Cable routing always evokes opinions like politics, but we listened to feedback from our dealers and customers and decided to make the change. Like the previous model years, we continue to use full-length housing, but this new routing orients the front derailleur housing exit downward, instead of up, and takes advantage of the integrated housing stop on high direct mount front derailleurs. This keeps the front derailleur shifting smoother for longer.
The frame retains the upper seatstay rack mounts, and you will soon see a new rack from Salsa that is specifically built for both fat tires and Alternator dropouts. It's pretty sweet, but I'll save the details for a separate blog post in the coming weeks.

Geometry Updates for Mukluk 2 & 3
In keeping with the all-season, all-terrain theme, we have tweaked the geometry of the 2013 Mukluk 2 and 3 to make it more versatile. We've taken cues from our venerable El Mariachi and adjusted the Mukluk to be a little more 'mountain bike' than previous iterations. The bottom bracket drop was raised slightly to add a touch of clearance, and the rear-center was shortened from 455 to 447mm. The headtube angle was also slackened out to 69.5 degrees for all sizes, and the length of the headtube reduced 10mm.
Together, this adds up to make the handling of the Mukluk a little snappier, quicker, and aggressive, which we find really adds to the experience in non-snow conditions/events. For those who prefer a little longer and more stable bike for snow and or loose conditions, or "just because", the Alternator dropouts allow for up to 17mm of rear-center (and wheelbase) to be added back into the frame, getting the handling essentially back to what the 2011/2012 frame versions featured. The headtube length adjustment lowers the handlebars about 10mm than the previous model years when running a ZS44 lower. When using a EC44 lower cup and tapered fork, the bars end up about the same as the 2011/2012 frames, due to the difference in lower cup stack height.

Complete Bikes & Framesets
To compliment the versatility of our Alternator-equipped Mukluk framesets, the component spec of all the completes also lends itself to the all-season, all-terrain intent of the Mukluk. All Mukluk completes and framesets continue to feature our feature-laiden Enabler fork. 2013 Mukluk 2 and 3 frames are also compatible with the new tapered Beargrease fork. With the exception of the the BFL front tire on the Muk Ti, all the 2013 Mukluks feature Surly Nate tires. The Nate tire is my personal favorite. It performs everywhere, in any conditions. The Mukluk Ti and Mukluk 2 feature the new ethirteen crank and exclusive spider that moves the chainrings out for improved alignment wih the cassette and creates more chain-to-tire clearance. The Mukluk 3 also features a "fat-corrected" chainline on a custom ISIS crank.

FAQ & Compatability
Here's some answers before you ask:
- Mukluks retain the same spacing, chainline, and tire clearance as 2012. The crankset solutions mentioned above eliminate chainrub with 3.8" tires on 82mm rims
- Mukluk 2's and 3's have painted-to-match Enabler forks
- For straight 1-1/8" forks headset: S.H.I.S. = ZS44/28.6 | ZS44/30
- For tapered 1.5" forks headset: S.H.I.S. = ZS44/28.6 | EC44/40
- Tapered fork (468 x 45mm) and EC44 cup reduce HTA (headtube angle) and STA (seat tube angle) both by 0.5-degree, and reduce BB drop by 4mm
- Post/Collar = 27.2mm/32mm
- Front Derailleur type is high-direct mount, top-pull, and mounts via Problem Solvers adaptor
- Frame fits 26 x 3.8" tires on 100mm rims, but drivetrain modifications may be necessary
- Frame fits Surly BFL on both 80 and100mm rims, but drivetrain modifications are necessary
- Mukluk 2 & 3 frames fits Surly Lou on 82mm rim, but Alternator dropouts must be adjusted to back 1/3 of range, and drivetrain modifications are necessary
- Frame DOES NOT Surly Lou on 100mm rim
- Frame fits Surly 29-plus Knard/Rabbit Hole wheels, but Alternator dropouts must be adjusted to full rearward position
- Enabler Fork clears all 3.8"/4.8"/29+ tires on 65/80/100mm combos currently known. (NOTE: Surly Bud on 100mm rim requires low pressure to squeeze past the caliper)
- Mukluk frame bags and fit are unchanged
I hope this post helps you understand our 2013 Mukluk offerings a bit better. They are incredibly capable and versatile bikes that will see you through many miles and adventures, on all kinds of terrain.
